See the commented lines. I need those Two lines. rest of the code is working fine. This file downloads the audio from YouTube. But I am not able to see any file size while downloading
Because youtube-dl doesn't have an option to display the size, you might want to look into ytdl instead, it can give you all the meta-data, like filesizes.
to install:
$ pip install pafy
...
$ ytdl [url]
